UHV DC Transformer Field Calibration Platform

Core technology and innovation

1. High-stability DC power supply technology for UHV site;

2. Fully automatic "missile upright" deployment structure, no assembly, no auxiliary equipment, the test deployment process does not exceed 30 minutes;

3. Intelligent induction hydraulic automatic control buffer technology, the erection process is stable, smooth and safe;

4. Airbag-type metal scale pressure equalizing cover, inflated and formed during the test, and deflated and contracted during storage and transportation "80OkV and above);

5. Test platform automatic getting on and off technology;

6. Platform expansion support and automatic leveling technology.

Technical characteristics

1. Multi-level voltage stabilization, stability is better than 0.03%6;

2. Full-wave symmetrical voltage doubler, ripple coefficient is better than 0.1%;

3. Coarse, fine, fine, digital output adjustment, fineness is better than 0.05%6;

4. Divided output, the lower limit of reaching the standard is better than 5% of the rated output intelligent control,

Automatic step-up, timing, step-down;

5. Wheeled traction self-propelled chassis technology (optional);

6. Double pressure "The pressure measurement adopts a slightly positive pressure nitrogen insulation structure, which is moisture-proof and non-toxic

Harm, safe storage and transportation, low maintenance cost.
